From a late 2015 find at this old mine, came some fine yellow Fluorites with dark phantoms. On this piece, many faces are dusted with tiny Chalcopyrite crystals adding an extra sparkle. In very good condition on the display side the back is contacted and incomplete. The small plate of matrix adds a nice contrast, and the corners and edges are sharp and clear. Largest cube is 3.3 CM diagonal in size and glows well with backlighting.
A well formed cluster of Pyrrhotite crystals showing the in process alteration on several faces. The terminations are unaltered and have the typical brassy color. This is a 1960 vintage specimen from Santa Eulalia which at that time produced many Pyrrhotites. These are now rare on the market. In good complete condition although the main crystal shows separations from altering, and would have eventually split apart, so this shows well a midstage transition.
Attractive and with an unusual esthetic, this is a densely packed matrix of lilac color Apatite. An older specimen from the classic Harvard Quarry in Maine, The druzy Quartz matrix hosts hundreds of small but perfect Apatites most being doubly terminated. In perfect condition and showing well the paragenesis of this locale, this was in the collection of the late Larry White. Two older labels give the locality as Mt Apatite (a more famous locale often incorrectly cited) but those labels are not correct, it is confirmed by Dr. Carl Francis and others as absolutely a classic Harvard piece. Choice and very rare in such fine quality.
A fine, vintage classic specimen of very large Pyromorphite crystals that are partly altered to Galena but are mostly still Pyro. The Kautenbach mine is one of the most distinctive of all European locales and the Galena Pseudomorphs are highly prized. Pyromorphite in sharp hexagons to 2.5 CM across with some zones of Galena coatings and alterations. The oldest label lists a date of 1880, and this is in remarkable condition given that age. Most crystal faces are sharp and complete but some minor edge wear is present. Excellent patina, the Pyro crystals are huge for the location and about as large as were found. Perhaps not a "beautiful" mineral specimen but to many collectors these old Pyros are real treasures. Choice.
Calcite in Fossil Clam
stock #Alec 19-286
Rucks Pit, Fort Drum, Okeechobee
9.4 x 8.8 x 5.7 (cabinet)
Pre Holiday 2017
A far better than average specimen of the remarkable Calcite in Clam shell fossil from the renowned Rucks pit. This was once a prolific small quarry and produced many of the Miocence age fossil Clams. Now closed to collecting and reportedly exhausted, this was a unique deposit. This example is a perfectly complete shell, well defined and showing the Clam exterior replaced by tiny Calcite crystals. The inner void is seen through an opening at the hinge and shows well formed gemmy amber color Calcite prisms to 3.1 CM long lining the inside. These were plentiful in the past, but fine, perfect examples like this were never common and are now especially desirable and rare.
This is a choice Shullsburg Calcite with the classic stepped Scalenenohedral crystals that have enlarged clear prismatic terminations. Far more transparent in person this has glassy luster and faint phantoms of internal Pyrite crystals. In excellent condition the only damage is the base and back lower edge area where this was removed. A choice older specimen, these are modern classics and this is like a textbook example of epitaxial alignment of prism faces.
Anglesite - Gemmy crystals on Galena
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oujada-Angad Province, Oriental Region,
3.7 x 3.3 x 2.4 CM (miniature)
Pre Holiday 2017
The type of Anglesite that is the most desirable from Touissit (or anyplace) are bright lemon yellow, gem clear prisms. This is a nice small specimen of that type, with fine color and contrast on the Galena matrix. There is a small chip on the largest crystal that is reflected in the price but this is not a big distraction. The clarity of the Anglesite is excellent, this is a facet quality crystal at a relatively affordable price.
Sections of stalactitic Malachite can be quite esthetic, especially when the form is more complex and with good color banding. This is an excellent example cut from materials collected in the 1990s. This style is now becoming rare with the "cauliflower" form. Complete edge rind all around, and polished on both sides.
